Specification of Letters Patent. Patented JuneZO, 1922 Application filed November 20', 1920: Seria-ING. 425,486.

To aZZ whom ?It may cancer IL:

Be it known that we, JOHN F. STECKEN* REITER and FRANK J. STECKENREITER, citizens of the United States, and residents of the city of New York, borou h of Brooklyn, in the county of Kings and tate of New York, have invented a new and Improved- Window Construction, of which the following' is a full, clear, and exact description.

This inventionrelates to window con: structions, and has for an object the' provision of a window Construction in which' the greatest possible lighting area is provided for a` given strength of window.

Another' object resides in the provisionof means whereby all parts of the wndow sashes are open for inspection and" painting at all times. i

A further object resides in the provision of means whereby there are no enclosed por tions on the window sashes in which condensation can take place and rusting result.

A still further object resides in the provision of a window Construction in` which the tendency of the sashes to rattle is' reduced to a minimum;

Another object resides in' the provision of a structure which is to a maximum degree weather and draftproof and fireproof.

A further object resid'es in the particular Construction and arrangement of parts here'- inafter described and claimed and shown in the accompanying drawings.

H'therto, some window sashes have been made of sheet metal and have involved' hol low enclosures in` which moisture may collect and cause rusting within the enclosures, and themetal becomes eaten through by this rustng action. Moreover, the lighting area provided is reduced. Furthermore, because of the fact' that the windows are hollow with'- in, these enclosed portions cannot be inspect edreadly and painted to prevent therusting action above mentioned Our invention rel'atesto certain features of Construction in which the above-mentioned objections are eliminated We providea window frame and sash portion. which are made of standard' stock metal forms, such' as channel bars, which can be assembled in the desired form and suitably connected to gether. Channel sections thus being used, the sashes are made narro'wer but of con'- siderably heavie'r metal, whilethey are aproxmately of" the same weight per lineal foot. The' s'ashest h-u's-'being made of heavier metal, makes' them practi'cally indestructible under ordinary use and' wear, and the sections being open, they are readily' inspected at any time, and; where" necessary, as readily pan-ted" toprevent rusting. Another most important feature of the invention lies in the provision of a resil'ient 'strip at' each side of each sash and between' each sash and the channelmember' or roove along which it' is adapted to slide' hese resil-ient strps are intended to accomplish several important things They are intended to make the s1iding 'movements of the sash' smoother by reducin'g' frict'io'n; tomake the Construction weathe-rpro'of, thus obvia'ti-ng: the necessity of weather-strips, 'and to make the window rattl'e proof;

A further' feature resides in' the' fact that by using stock'chann'el bars or similar forms we are* able to obtain the same' strength for the window constructionwhile usingsmaller sized' metal members, sothat the lighting area* ofthe' sash isconsiderably increased for the'- same strength of window.

Other features of' the invention will' be 'appa'rent from' a` consi'deration-of the following description when taken in connection with the drawings; I

The invention is illustrated ,in the draw'- ings, of which-'- F igure I isan elevati'onof the window sash with the frame in position: v

' Figure 2" is a section taken onthe line 2 --2 of' F gure 1 and& i

' Figure 3 is a' section taken on the line.

of Figure l f As shown in Figure, this metal construction* is used in connection with the* ordinary wall or' opening I in` which the window frames are disposed These frames are, as shown' in' the figure, made of vertically eX-tending channel bar members 2 which are connected to' similarly-shaped channel bar members 3 in' such a manner as to form a vertically extendi'ng' hollow jamb, These frames are built into the walls of' the building adj'a cent the' window ap-erture and are connected'. to ether either by weldng, rivetn'g or boltng at their' abuttng portions Across the' top` of' the window* opening a extending jamb members above mentioned.

. any suitable manner, such asby riveting or The bottom portion of the frame, eXtending between the vertical sash portions, is made in the' form of a sill. This sill member is in the form of a metal channel member 5. This sill is connected at its end portions to the vertically extending frame membersgin by bolts. The upper face ;of the sill member 5 is formed with the usual outwardly'sloping surface 6, an intermediate surface 7 and an inner horizontal flat surface 8. The surface 7 is separated from the surfaces 6 and 8 by vertically eXtending shoulder portions 9 and 10, which are provided for a purpose hereinafter to be described.

On the inner face of each of the vertically` extending frame members are disposed sash guide members along which and between which the window sashes are adapted to slide. The inner and outer sash guide members are shown in the form represented bythe numeral 11 andmay be connected to the frame members in any suitable manner. These are made of metal of any stock form desired. The intermediate sash guide members, as represented b the numeral 12, are metal bars of the requred dimension. Channel bar 3 is connected to the extensions of the sides of the vertically eXtending frame member 2 at 29 and 30. These two vertically eXtending projections, by being built into the wall, act as two continuous anchors to hold the window rigidly in place.

In the channel portions formed between the members 11 and 12, the window sashes A and B are adapted to slide inthe usual manner. The upper window sash is represented by the letter A and the lower, by the letter B. Each of these sash members comprises rails and stiles. The rails of each sash are in the form of metal bars, represented by the numerals 13 and 14:, with the channel portion facing outwardly. Similarly, the stiles of each sash are channel bars 15 and 16. These stiles and rails are suitably connected at their abutting end portions in any desired manner, such as riveting or by being welded together. The window panes 17 are held in position inthe rectangular opening between the stiles and rails by being disposed between metal bars, such as 18, which may be connected to the rails and stiles in any desired manner.

It will be observed that the rails and stiles are formed of channel members of such dimensions as to give them any desired strength andyet, at the same time, form a window sash which has no enclosed portons within which moisture may form to cause the metal to rust. Practically the entire metal surface of the sash is open for inspection, and can be painted whenever it is necessary. By reason of the use of stock channel forms, any desired strength and -weight of window sash may be obtained by the use of members which are smaller in size than hitherto has been the case, so that the light opening is proportionately increased.

With respect to the upper frame A, it

will be observed in Figures 2 and 8 that there is disposed between the sides of the stiles 15 and 16 of this sash and the vertically extending sash guide members 11, a thin resilient strip of metal 19, preferably phosphor bronze, although any other suitable material may be used. This strip may be secured, if desired, between the sash guide member 11 and the vertically eXtend ing portion of the frame, such as the member 2, or

may be connected in position in any other desired manner; the idea being that this strip will bear resiliently against the rear face of the stiles of the sash and by reason of its resiliency will prevent any lateral Vibration of the sash and, at the same time, make a reasonably tight joint so as to make the structure weatherproof. This strip, with respect to the upper sash A, extends from the top' of the frame opening to a point below the bottom of the upper sash when in its upper position, as shown in F igure 2.

A similar set of strips 20 is provided be tween the metal bars 12 and the rear of the lower sash' B. These strips are shown in F igures 2 and 3. The sets of strips 20 eX- tending from the bottom of the sill member 9 to a point above the upper end of the sash B, When the sash B is in its normal closed position, as seen in Figure 2.

It will be noted that the bottom channel member 21 for the lower rail of sash B has which, 23, is longer than the other, 24:. The disposition of the long and short faces of these channel members 22 are reversed on the upper and lower rai1sabove mentioned, so that when the sashes A and B are in their closed position these long and .short faces of the channel members contact with each other, as shown in Figure 2, to make an exceedingly tight joint, which is drafti has two laterally extending faces, Vone of and weatherproof. However, although this joint is tight, when the windows are separated there is presented on each rail a channel bar which is entirely open, having no enclosed places, and which can be inspected and painted readily without disassembling the parts. A finger lift of any suitable form, such as 25, is applied in the sash near the lower rail of the sash B. The windows are supported by chains 26 running over pulleys 27 and balanced by the usual sash weights 28 which are disposed within the frame members formed by the channel bars 2 and 3 above mentioned.

It will be observed by a consideration of this description that we have provided a window Construction in which the window sashes have the desired strength with ,a maximum lighting area, and of which the metal is so formed that no enclosed spaces exist, all surfaces being open so as to be readily inspected and painted. The fact that the entire structure of these windows, excepting the glass is made of ordinary stock metal shapes, makes the window one of extreme Simplicity; having no soldered or brazed joints or connections makes it positively fireproof; all sections being made of heavier metal than the hollow metal windows -of this type now in use, makes it practically indestructible through ordinary wear and use; the sections composing the sash being narrower, it' gives a larger lighting area for any given size of window opening, and it is free besides from any condensation pockets that would cause any hidden rusting, because all sections are open to inspection at any time. Furthermore, the resiliency of the resilient strip makes the sliding movements of the window smoother and comparatively frictionless, besides making the window Construction draft-, rattleand weatherproof.

Again, the vertically extending frame members 2 and 3, having the back edges of the front and rear sicles projecting into the wall for the full height of the vertical frame members, gives the window frame the maximul of anchorage.

This metal window Construction is highly advantageous and answers a real need when considered in the light of all these advantages.

What we claim is:

1. A window sash Construction having stiles and rails, which comprises a weathertight joint between adjacent rails when the window sashes are in closed position, which joint comprses U-shaped channel members, the base of one member fastened to the lower rail of one sash and the base of the other channel member fastened to the upper rail of the other sash, the legs of the each U member extending horizontally outwardly toward the legs of the other U member, one of the legs of each U member being shorter than the other, these legs being so disposed that the short leg of one member, when the sashes are in closed position, contacts with the long leg of the other member, and vice versa, to provide two spaced Contacting surfaces disposed in horizontal planes to make the joint airand watertight.

2. A window Construction having a sill' formed of an integral single portion of cast metal having a pair of spaced, vertically extending shoulders thereon and downwardly and outwardly sloping surfaces adjacent each shoulder, a lower rail of a window sash adapted to co-operate with the sill, said rail formed of a U-shaped channel member, the legs of the U lying in vertical planes closely adjacent the vertical planes of the shoulders and hearing against the shoulders tightly when the sash is in its lower and closed position.

3. A window sash construction having stiles and rails, which comprises a U-shaped channel member disposed on adjacent faces of adjacent stiles when the sashes are in closed position, the legs of each member eX- tending outwardly from each other, one leg of each member being shorter than the other leg and reversely disposed relative to each other so that they overlap to form two contacting horizontal surfaces when the sashes are in closed position to make the joint weatherand water-tight.
